Does a 6 x 12ga wire nut exist?

I've got a junction box that I want to tie 6 12 gauge wires together (1 in, 5 out). I took a look at Home Depot last night and picked up a 6"x6"x4" junction box which I can only imagine is plenty big to house this kind of connection. However I didn't see any wire nuts that could handle tying in 6 12 gauge wires (the biggest one I saw could only handle 5 12 gauge wires). Does such a wire nut exist? If not then maybe another option is to use 2 wire nuts within the box. The first would tie together the incoming wire + 2 outgoing wires to fixtures, and a fourth, short wire out to the 2nd nut. That 2nd nut would tie in that short incoming wire from the first nut + the remaining 3 outgoing wires to fixtures. I know that's not particularly pretty, but would it meet code (NEC)?
